Hi,
Familiarizing myself with Tkinter I'm stuck trying to fill a Canvas
with an image. I believe the class I need is PhotoImage rather than
BitmapImage. But I have no luck with either. The PhotoImage doc lists
available handlers for writing GIF and PPM files. It doesn't say
anything about r

Tkinter makes it very easy to drag jpeg images around on a
canvas, but I would like to have a "target" change color when
the cursor dragging an image passes over it. I seem to be
blocked by the fact that the callbacks that might tell the
target that the mouse has entered it (, ,
even ) aren't call

Try calling the canvas's delete method with the old rectangle before
making a new one.

You aren't drawing, but **creating** rectangle objects, as

Hey everyone. I have been working with python for a couple years now,
but just recently built my first program with a GUI. I decided to
start with Tkinter since it is included with the base package,
although wxWindows will likely be my next choice. Tkinter seems to be
pretty slow for my needs.
I want to when create text box with
objid = self.canvas.create_text(x, y, width=event.x-x, text='')
how can i bind KeyPress to objid?
I want that text appear on canvas as i write it.
dont know do I need to use self.canvas.create_window, and put in that window
Tkinter Text widget.
Or I can do it

Hi all!
I have just finished my tkinter text editor, learning tkinter purpose.
Now I want to learn canvas so I want to make my paint program, I think that

Is there any good tutorial for mvc in python or

Hello. When I tried to make Tkinter canvas widget respond to
MouseWheel event on Windows XP, I failed. The canvas just doesn't
receive MouseWheel event. I used bind_all to find out which widget
receives this event and the result showed that only the top Tk widget
gets it. This is really ann
What is the best way to print a graphic image contained within the

way?

not really; the canvas is double-buffered, but it regenerates (portions of) the

if you want to draw in a separate buffer, and use that when updating the w
Is there a way that using Tkinter I can pre-render the canvas then draw

Is this doable or any suggestions on an alternative.Maybe another way to
display my grid on top of the canvas?

I'm trying to display a picture on a Tkinter Canvas. It seems to work
fine the first time that it is displayed. However, subsequent times
running shows an error like this:

got confused by x, y coordinates in Tkinter canvas.
from left to right, does X increase?
from top to bottom, does y increase?

Let's find out! This program creates a series of rectangles, with the color
going from black to nearly white. White corresponds to higher x and y
coordinate values. So the answer to your question can be seen in the output
of the program.
import Tkinter
c = Tkinter.Canvas(width=220, height=220)
